SANDY HOOK – An unexploded ordnance was found on land next to the Seastreak Ferry dock Wednesday afternoon, authorities said.

National Park Service spokeswoman Daphne Yun said the ferry has been diverted to Highlands and Hartshorne Drive has been closed. Authorities have been called in to dispose of the ordnance, Yun said.

Naval Weapons Station Earle spokesman Mike Brady said the base's explosives ordnance disposal detachment is responding to Sandy Hook to investigate what kind of ordnance was found and will determine what to do with it.

The ferry dock is in the Fort Hancock area of Sandy Hook, Yun said. She did not know who found the ordnance or how it got there.
